C2P is as it sounds it converts a chunky screen memory into planar using multiple mem copies etc.

The 68EC020 in the A1200 when used with FastRAM is faster than the Akiko.
The Akiko is faster than a 68EC020 when used with ChipRAM (which is all the CD32 has).

I think the philosophy of putting the C2P in the Akiko was :

RAM is VERY expensive, the CD32 probably won't have any Fast RAM. We're designing a CD controller chip anyhow. Why not "bung it in"?
